Rear tail lights not working

I have a 1993 1/2 ton 4x4 with no rear tail ligts. It has a drawtite brake set up and the wires are a mess. I would like to remove the drawtite kit and just wire it back to stock. I have the manual on the truck but the diagram does not help me.Any one have a photo or discription of the wire set up for stock?

Sounds like you have a rats nest to deal with, but I do know that trucks with your style taillights have problems with the circuit boards, just take a look within the socket the bulbs go in, if there is any scorching they are shot, you can pick those boards up at most junkyards for cheap. it may help instead of the headache of rewiring

Yes all the tail lights are new, along with the sockets. When wee pulled the bed off for the paint I unpluged the wrong plug. (Dumb A$$) pulled lots of wires out. I dont need the drawtite so I want to re-wire with the factory harness.

Bingo.... The area under the bumper is what I need what does the harnes look like. The drawtite was put on in 1993. I think they cut the harness grounded it then put the drawtite on... Any idea what years are the same? We have one you pull it in my area and they have no 93's. Wire color would help....

When you say you have no taillights, do you mean just the taillights, or do the turns/stop and reverse not work either? The wiring is quite simple. You should have a four conductor cable coming down the left frame rail to the bumper. Light green is reverse lights, brown is taillights, dark green and yellow are stop/turn. I can never remember which side is which. Doesn't matter. There was, and hopefully still is a plug behind the bumper so you can isolate all the rear lights, including plate lights, from the truck. Use a test light or a meter to confirm all four wires work properly before going any further. If the taillights (brown wire) don't work, you need to fix that first. It may be as simple as a blown fuse. Once you get that working, it's just a matter of tracing backwards (forward LOL) from each light assembly to the plug, and matching the colors up. Remember to tie the plate lights into the brown wire. Its possible there are two more wires coming down from the front of the truck. These would be for electric brakes, and battery charge wire. I don't know if GM had full tow package wiring in 93 or not. If they are factory, the would likely be blue for brakes and orange for charge. If they are there, just cut them off, and tape the ends well.

Glad you were able to fix the problem. Don't know if it would have helped, but the e-trailer.com site has lots of good harness/installation info and some great videos like this one:
